To all whom it may confirm.

Be it known that 1, Woman l l ms'rwmt, a citizen of thc l nitvd Stall-s, and a rosidcnt of the city of Nuwport. in the county of (ampholl and State of Kontl-icky have invented certain new and uscful Improve- !ncnls in Looks, of which thc following is a sperification.

The scveral features of mv invention and the various advantages resulting from their use conjointly or otherwisc will be apparent from the following descri tion and claims.

In the accompanying rrawing, making a part of this spccifimltion and in which similar characters of rciercnco indicatc cot-rd sponding parts,--ligurc 1 is a side elevaswitch being: act to make the lock scrvr as a night latch.

I will now describe my invention in detail.

Tho loclocase A is traversed by a spindle ll to the ondr of whiz-h ordinary knobs or handles are secured, in order that tlu only bolt (I of the lock may be operated either from the outsidc or inside in the usud-l' vay,

tho bolt being shot by the spring C The I spring (7* is compressed between the hack of 3' the bolt. 0 and the guide post G. From the hack of bolt 0 a stem pro jerts. The rear end portion of this stem (l' is in an opening in the guide post C, and is slidablo through the post. The sprin r C embraces this stem C and is ornnpressot between this stem and the back of said bolt C. This $lQI1l1I-C guides the bolt 'lhc bolt is operated from the haudlo spindle B by the arm D.

This arm I) has at one end the raised por tion I) which engragcs with the arm C fastonrdlo the bolt The fiIllLD is kept in aluminum and is guided by the guide post D and is shot by tho spring D. Th9v spindle ll oporates directly the huh l3 carrying the arms B, BK which rcspectivcly etwage adjaccnt arms D* D of the arm I). This hub B is located in a slot D (if the bolt arm D.

Located bclow the bolt: arm D and pivotod within thc case at E is a lover E hav ing; a rcc-tangular opening E and a semirircular' opening E communicating with og'icning E. arc of such proportions to pcrmit the free turning of pin F projecting horizontally from tho semicircular disk F, in a radius from the (router of pi \ot F of disk F. The

Those oionin s E and E disk F is journalcd iu ('tlSl' A on its hollow pivot F. This pivot F" is tl1roadml m thc IllSldl': to rw'rirn the headed pin H. This pin Il may have the inserted end shaped as H being cut oil fiat on two sides, or,any other dcsircd shapo in cross section I is adaptcd to fit and ongag'c such shape of tho mu! l'l", hm tho and may, when dosircd. ho [)ctfcclly smootln in which caso, nobody from tho outside can turn the pin H with a hay. r

A switch K on its collar I is interlocked in thc disk l by means of a groove F cut into disk 1 and a projection K on K to fit tho groorc l This switch is hold in place A key tightly by the hoadod pin H being screwed down tightly. A thumb piece H of the pin enables the pin H to be screwed to place or untzcrewcd by the spring F. The disk F boing semicircular, the shoulders F F thus formcd t-ornc in contact with the pin F, 96

0st L is 100 adapted at the proper moment to 1'01) and engage with the coincident gates M of the disk tumblers M, mounted-u 0n the sleeve M, fastened securely in case These disks are free to move around the sleeve M but are kcpt in place by collars M which embrace and fit tightly u on the sleeve. Thin washers M are placed etween the disks and collars to make the movement of the disks free. The top disk tumbler M is not mounti ed on the sleeve M, but is made with a cylinder M which passes through the sleeve M and is free to revolve therein. Tlils disk M is the driving disk tumbler. With the cylinder M another cylinder N is interlocked by some suitable means. One kind of such means consists as follows: A ridge N of cylinder N locks in the groove M of cylinder M. To the cylinder N a pointer N is attached. This pointer is on the inside of the door X and points to the numerals on the dial P. To the outer end of cylinder M is interlocked, by means before described, a cylinder R, Whose outer end is provided witi a. flange R This flange R is perforated near its circumference bv holes R Passing through the cylinders It, M and N is a rod S threaded on its inner end at 53'. To the outer end of rod S a disk 5 is fastoned, which has on its inner face, pins S which engage in the perforations R in flan R To the peripheral edge of disk S handle S is fastened. By this handle S, the disl: is rotated. This handle S 'also serves as a pointer. On the inner end of rod 8, at S a nut S is screwed, this nut having a chamber S in which a spring 5 placed, and fitting loosely over 8*. This nut S being screwed against the end of the cylinder N tightly brings this cylinder N and the cylinder M and the cylinder R and the disk S ti htly together. \Vhcn the disk S is revolved: it revolves the cylinder It by means of the pins S holding in holes It", and the cylinder It bein locked in cylinder M revolves the tumbler 1 which has a projecting pin M on its under side, which latter engages with the iins M. inserted in the faces of tumblers I. The combination of the lock is determined by these pins M" when they are first inserted in the disk tuni' blers. The user of the lock can never change the position of these pins, but must be informed of the exact combinations by the manufacturer. Let it be supposed that the tumblers .M are set up on the numbers 1), 3, 10 and 4, or in other words,-nine, three, ton and four distinct movements must be made before all the gates M can be brought in line with each other and the post L be permitted to engage with them. The cylinder N being interlocked with the cylinder M turns arm N pointing to the numerals on the dial.

The combination can ncvcl' be changed, but by unscrewing nut S a. little distance, the stem S can be pullcd out. which throws the pins S out of holes It, then by turning disk S by handle S", the pins S cngage in a different set of holcs It. Meanwhile the spring S keeps all parts interlocked while thisis being done by pressing against cylinder N. This action throws handlc S out 01' line with pointer N thereby changing the combination to be read on the outside dial. The memorandum of the combination to be worked by reference to the dial is carried by persons using the door. This outside dial may be changed as many times as there are perforations in the flange R The switch K is so fastened on the collar K (which is interlocked in disk F and held tight by the bead pin H, II, which is screwed into pivot F) as to be in line with the pin 1 on the semicircular disk F, in order that said pin F may be vertically above the axis of disks F, t s seen in Fig. 4-, when switch K is perpendicular as represented in Figs. 2 and (3. In this position of pin F, the lover I), as shown in Fig. 4, is lifted clear of the raised portion D of bolt arm I) and also of the wing C of arm C which is a part of bolt (l. In this position, as shown in Fig. 4, the lock is used as an ordinary spring bolt, which allows the bolt to be drawn back by the handle, or if the door is open and goes shut, the bolt (l operates alone by its spring 0 \Vhen the pin F is in the position shown in Fig. 5, the switch takes the position as shown by the dotted lines K, as shown in Fig. 6. The lock is now used as a combination lock. The pin F'- being free in the opening E, the lever E can drop and free portions l)- and C as soon as the combination is restored, letting the post I, fall into the gates M of the tumblers. The lever E is raised and locks the bolt by the tumbler M, through the agency of the post L and the pivoted rod lever If, connected at L to the lever E, as soon as the tumblers are scattered by turning disk S. In this osition of pin F if the combination is not mown, the disk F may be turned to the position as shown in Fig. 4 by a key, as in Fig. 2. Further movcment of the disk F is prevented by the pin F which is located in the lock-case A.

\Vhen the disk is so turned by the switch K, as shown by the dotted lines K" in Fig. t', thc pin F rests in the opening IC 111 lever E, as shown in Fig. 1, and the shoul- (lcr of said disk F is against pin F, which stops further movement in that direction. The lever [C is now locked by'the pin E and cannot drop, therefore the combination is made useless, and the door cannot be opened from the outside unless the disk turncd byva key to either of the other two positionsJFigs. 4-.and 5.

Attention is called to the fact that the screw shaft II can, by rotating it, be readily withdrawn and a new and differently formed end for the engagement of the removable key can be made. hen such change is made, the old key cannot operate the bolt. In this way, the lock may be easily made safe against bein opened by one who has possession of the ormer key, {lflflWhGL should not have entrance to the room, etc.
